Embedded Computing Design

As smart devices are becoming more popular and their demand will only grow in the coming years, we developed a LED display smart speaker with I2C control using a typical GreenPAK design. This design allows the switching of dynamic LED indicator in the smart device depending on its modes: Standby (idle) mode, Listening mode, Thinking mode, Responding mode, Meeting Mode, and an indication of on/off mics of the device. Mode switching is implemented by I2C commands, by overwriting only one register.
